The figure is made up of 2 squares of different sizes. The area of the small square is 50% of the area of the big square. The overlapped shaded area is 4 cm
2. The area of the unshaded small square is
14 the area of the unshaded big square. Find the area of the small square.

Total Area |
1x3 = 3 u |
2x3 = 6 u |
1x3 = 3 u |
Shaded Area |

Unshaded Area |
1x1 = 1 u |
4x1 = 4 u |
3x1 = 3 u |

12The difference remains unchanged.
LCM of 1 and 3 = 3
Shaded area
= 3 u - 1 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Area of the small square
= 3 u
= 3 x 2
= 6 cm
2 Answer(s): 6 cm²
